NOTE
The heat generated by the PV modules reduces the capacity of the sys-
tem. Sufficient ventilation of the PV modules minimizes this loss of
power.
High module temperatures decrease the system performance.
A generous as possible air gap must be planned with a
vertical orientation to allow ventilation of the modules
(counter battens as with a normal roof).
1.
Attach the slats of the substructure with adequate fastening means
directly on the roof.
2.
Reconcile the sub-construction on the location of the mounting
brackets with the photovoltaic modules (see raster plan).
3.
Seal the free cross-section between the slats at the eaves with bird
protection screen.
4.
If possible, modify the ridge as a fan ridge in order to dissipate the
heat.
5.
For the transition from the lower edge on the tiles use the eaves skirt
(lead role or Mageflex® band).
CAUTION
The certification of the modules according to IEC 61215 (ed.) is valid
only in connection with a defined substructure!
Use mounting boards with 30 x 100 mm cross section for
the substructure
softwood Class II
Only with this minimum cross-section of the mounting
boards can the introduction of force of the screws be
guaranteed.
Attach the mounting boards on the roof construction with
approved and suitable connection means
